To all whom 'it may concern:

Be it known tha-t we, ANDREW F. MILLER, MARK IIUoGiNs, and CHARLES JENKINS, citizens of the United` States, Aresiding at Columbus in the count of Franklin, State of Ohio, have invente a new and useful Water-Motor, of Which the following is a specification.

This invention relates to fluid pressure motors and has for its principal object to provide a motor of simple and economical construction which may be readil attached to the faucet of a water pipe an oplerated by the pressure from a city main for t e purpose of actuating a washing machine, sewing machine, or the like.

A further object of the invention is to provide a motor having an oscillatory iston and provided with inlet and exhaust va ves which are operated directly from the piston, thus dispensing with the usual valve gear and its connections.

A still further object of the invention is to provide a yieldable connection between the valves and the piston, so that after the valves have been shifted, the piston may still con- .tinue its movement without coming to an abrupt stop.

A still further object of the invention is to provide a yieldable or cushioning connection 'which in addition to permitting opening and tact with the water.

A still further object of the invention is to so construct the cylinder and valve casing as to readily permit the removal of the upper portion of the casingv so that access may be iad to the entire mechanis With these and other objects in view, as will more fully hereinafter a /pear, the invention consists 1n certain nove features of c011- struction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the s irit or sacricing any of the advantages o the invention.

In the accompanying drawings z--Figure 1 is a sectional plan view of a Water motor constructed in accordance with the invention'. Fig. 2 is a transverse sectional view of the same on the line 2-2 of Fig. 1. Fi 3 is a transverse section on the line 3-3 o Fi 1, Fig. 4 is a detail elevation showinsne o the yieldable connections and its gui l Similar. numerals of reference are e111- ployed to indicate corresponding arts throughout the several figures of the raw-` g.lhe cylinder is formed of two mating sections 10 and 11, each in the form of an in complete circle. These are securely fastened together b riveting, soldering, or the like. The cylin er is provided with projectin bolting ears 12 by which it may be secure to a suitable base. The central portions of the cylinder sections are bored for the recep# tion of a shaft 13 over the upper end of which fits a cap gland 14 in order to prevent the passage of dust and dirt, and at the same time to prevent leakage, The threaded opening in the lower section of the cylinder receives an ordinary gland 15, through which the shaft extends for coupling to the washing machine or other device to be operated. l g

venting the escape of the actuating huid.

around the shaft.

Secured to the open side of the c linder is a valve chest 22 carrying a vertica ly dis osed artition 23 which forms the outer ead o the working space of the cylinder, and in this partition are formed a number of inlet and escape ports, these being arranged side by side in pairs. Extending from the outer face of the artition 23 to the outer end of the valve cliest is a horizontal parttion 24 which divides the outer portion of the chest into an inlet chamber 2 7 and an exhaust chamber 28, these being provided` with suitable connections for the admission andv escape of the operating iiuid. This valve chest may be removed when necessary to expose all of the Working parts of the' motor without opening the cyhnder.

Projecting inwardly from the vertical partition 23 of the valve chest is a plate 3.0 on

' the opposite sides of which are fitted cup same construction, one valve latter extendin leathers 31 held in place by plates 32 and a transverse securing bolt 33. These memb ers form an. abutment that` divides the working space of the cylinder and which bears so tightly against the hub ofthe piston wing and the curved wall of the c linder as to prevent leakage from one si e lto the other.

That portion of the partition 23 whichA forms the base of the inlet chamber 27 is provided with two inlet ports 35 and 36 and these are arran ed to be opened and closed by a pair of va ves 37, 38 of precisely the eing moved to open position while the other 1s simultaneousl moved to closed position. The stems o these valves are connected to a lever 39 that is pivoted on a pin 40, the through openings formed in the outer Wa ofithe chest and in the horizontal partition 24. The outer end of the are two cross bars 50.

' In that `-ortion of the pin is headed and fits in an enlar ed threaded s, opening into which is tappe a headless` screw 41, a blind gasket 41 eing preferably introducedbetween the end of the pin and the inner face of the screw for the purpose of preventing leakage.

artition 23 which forms the ase of the ex aust chamber 28` are arranged two exhaust ports 44 and 45 which may be opened and closed by a pair of valves 46 and 47 of precisely the same construction, one valve being arranged to move to open position, While the other moves to closed position. The stems of these valves are connected to the o posite ends of the lever 49 that is mounte on a -pin 40 of the same construction as the corresponding pin which su orts the lever of the inlet valves. Exten ing across the inner portion of the valvechamber, or that portion of the chamber which' really forms a rpart of the cylinder, hese cross bars are provided with a flanged opening for the reception of a cylindrical casing 51, and the inner end of the casing is provided with an enlarged inte raldisk 52 that is arranged to bear against t e inner face of the valves. ln each casing 51 is a helical compression spring 53 against which bears an annular flange 54 carried by a in 55,' which latter extends out through a g and 56, the inner end ofthe gland bearing against the gasket 57 that is seated against a shoulder formedv within the casing and between the gland and the outer face of the gasket, a liquid proof` packing 59 is interposed. This spring casing 51 may be lledwith'any suitab e lubricating material for .the purpose of preventing undue Wear and the sprmg will e fully rotected from the action of the Water v'vhic is used as an operating means.

i, In o eration, the inlet valve37 being open,

and in et valve 38 bein closed while exhaust valve 46 is closed an( exh'aus't valve 47 is open,- the piston wing bein assumedto be ig. 1, water or4 in the posltion shown in other actuating fluid will enter the inlet chamber 27 and will pass through the inlet port 35, while the dead water in advance of the piston wing will exhaust through the port 44 to the exhaust l chamber 28. The entering volume of water will then force the piston wing to travel around clockwise until the piston wing strikes the pin .55 shown to the ri ht of Fig. 1. The first eiect will be to slight y com ress the spring 53, thereb forming a cus ion which will gradually chec the movement of the iston wing. As the spring continues to yield, movement will be transmitted to the spring casing 51 and disk 52, and will thus act on the two valves 38 and 47, moving the valve 38 to open position and the exhaust valve 47 to closed position. This movement will be transmitted through the two levers 39 and 49 to the mating l gvalves at the oplposite side, causing the -inlet valve'38 to c 'inflow of water, and the valve 46 to open, so

ose and thus shut oil the that the water is now free to esca e t rough the port 44 to the exhaust cham er, Whereupon the movement of the piston wing will be reversed. In all cases, t e movement of the piston wing Will not be abruptly checked,

but will gradually cease as the sprmg is comj pressed and then assisted bythe ressure of the entering Water, the spring wi start the piston on its return stroke.

The main shaft may to the device to be operated, and as no valvev mechanism is employed for transmitting movement fromV the shaft to the valves, the motor may be made and kept in Y re air at very small cost.
